First of all, congratulations on the release, I'm very excited to get going with my freeplay character. I usually find a lack of central storyline boring, however, so I have a suggestion: why not implement a feature that lets us create our own Zone narrative? Not sure if this is even possible, but I'm imagining a PDA diary (or, more primitively, a simple feature that allows the player to type words on screen) where the player can record their experiences whilst in game.
I plan to do this anyway with a wordpad document, but minimizing the game would kill my immersion, lol. Anyway, just figured I'd shout that idea out. Hope this mod goes far!
